thatdnaguy, If you work on the command-line in Linux a lot, find + exec is your friend.
"I have many copies of MYFILE because my project got sloppy over time. Are they different?"
find . -type f -readable -name "MYFILE*" -exec md5sum {} ;
Also handy for if temporary files get out of control and rm chokes.
find . -type f -readable -name "*.temp" -exec rm {} ;
